The WSR-88D Doppler radar can detect motion within the atmosphere by measuring small ___________ between the emitted and returned electromagnetic (EM) pulse.

Frequency changes are caused by:

• the Doppler effect

• sound waves

• light waves

• electromagnetic pulse

The Doppler shift is change in frequency or _________ moving relative to the wave source.

Doppler radar works by emitting electromagnetic waves that strike an object, scattering and reflecting back to be read as _____________.

Doppler radar produces an image and measures the ________ of the target.
